caniusethat is a wrapper around PyZMQ that enables easy RPC (remote procedure call) functionality.
This module uses pickle to serialize and deserialize data.
From the Python documentation:
The
picklemodule is not secure. Only unpickle data you trust. It is possible to construct malicious pickle data which will execute arbitrary code during unpickling. Never unpickle data that could have come from an untrusted source, or that could have been tampered with.
Only use caniusethat on your local machine, or behind a firewall that is configured to allow connections only within your local network, or in any case from machines you trust.
caniusethat can be installed via pip:
pip install caniusethat
